What is BS 5250?
BS 5250 – currently the 2016 edition – is the code of practice for controlling condensation in buildings. It provides building designers with guidance on safeguarding the health of occupants by considering likely sources of moisture, avoiding the build-up of excessive moisture, and preventing mould growth and condensation.
BS 5250 states that the designer should take account of the following moisture sources in buildings:
- Water incorporated during the construction process (including precipitation)
- Precipitation after construction
- Water vapour arising from the occupants and their activities
- Temporary condensation occurring when cold weather conditions are followed by warm, humid weather
BS 5250 also emphasises the importance of well-sealed ceilings to curb the transfer of moisture into a roof space by means of moisture-laden air. This means:
- The avoidance of gaps and holes in a ceiling
- The sitting of access doors or hatches into the roof space away from moisture-producing areas such as bathrooms or kitchens
- That hatch covers must be effectively sealed
- High levels of workmanship
